We are using Exchange Direct Push.
 
We use two ISA 2004 Firewall servers (Network Load Balanced) in our DMZ, (in a workgroup config), backed off to, two front-end servers Network Load Balanced, we have three clustered EVS behind the front-ends.
 
Front-end and Back-end servers are in our internal LAN.
 
ISA 2004 servers in the DMZ. (workgroup)
 
TCP 443, opened into the LAN.
 
Same certificiate used on all front-end and isa servers.
 
ISA 2004 OWA Published Rule setup on ISA.
 
We use XDA II/IIS/Mini IIs and ActiveSync

Is anyone using the new exchange direct push technology yet?
 
I was told that to enable it I would need to map 443 from the Internet to my Exchange server, and also that I would need an SSL certificate installed.
 
I'm wondering if anyone has done it with only 1 exchange server? I have 1 exchange server behind 1 firewall. No seperate exchange front end, no seperate smpt server, and we dont use owa, so no owa server. Just 1 exchange box.
 
I always have concerns opening ports up, so curious what other people are doing. Would you only do this if you had a front end exchange box in a DMZ?
 
 
 
 
 
Thanks in advance,
Jon
